CLOSURE APPARATUS.

This invention relates to apparatus for effecting closures and moreparticularly to apparatus designedfor use in connection with receptaclesand the like which are closed by means of a blank, the edges of whichare crimped about an adjoining'edge of the receptacle.

It is an object of the present invention to provide an apparatus whichwill effect such closures rapidly and effectively.

Other objects and advantages of tl1e invention will appear hereinafter.

A preferred embodiment of the invention selected for purposes ofillustration is shown in the accompanying drawings, in which,

Figure 1 is a plan view of the device,

.Figure 2 is a side elevation,

Figure 3 is a section on the line 33 of Figure 1, and

Figure 4 is a detailed sectional view showin one of the arms inoperation.

Tteferring to the drawings the closure apparatus comprises a base plate1 provided around its outer periphery with a plurality of bosses 2 ineachof which is pivoted an arm or lever 3. Atone end the arm is providedwith a head 4: which is grooved to provide a face 5 adapted to engagethe edge of the closure blank as hereinafter explained.

The plate 1 is also provided with a flange 6 which may be cylindrical inshape forming a cup. 7 at the center thereof. The flange 6 is providedwith a series of slots 8 through which the ends of the the inside, ofthe cup 7.

Mounted loosely within the cup is a cup shaped member 9 having a roundedbottom 10 and provided with a cylindrical flange 11 extending upwardlyinto engagement with the under faces 12 of the ends of the arms ,3. Thecup-shaped member 9 forms a cam by which the arms 3 may be operated andis provided with' a lever or handle 13 by means of which the device maybe operated.

For purposes of the present description of the invention the apparatusdescribed has been shown in connection with a metallic receptacle 14which it is desired to close with the metallic blank ,15. The blank 15may be provided as illustrated with a U-shaped flange 16 adapted to-fitover the beading 17 at the upper edge of the receptacle. The

arms '3 project into sired, a gasket 19 of rubber. or other suitablematerial may be laid in the flange 16. in-

order to more effectively seal the edge. It will be understood that theforegoing is illustrative merely of one form of receptacle and closureblank. with which the apparatus described may be used and that, as

will beapparent, the apparatus of the invention may be used effectivelywith other types of receptacles and closure blanks.

lVhen in use the receptacle to 'be closed 7 may be covered with a blankwith which it is to be closed and the closure apparatus may then belifted by means of the handles 20 and placed on top of the closure blankas illustrated in Figures 2 and 3. In this position it will be observedthat the faces 5 are adjacent the depending edge 18 of the blank andthat an inward motion of the heads 4 caused by lifting the inner end ofthe arms 3 will cause a bending and crimping of the edges of the blank.At the same time a compressive force will be exerted between the faces 5and the faces '5 of the baseplate tending to compress the gasket 19 toform an effective closure and seal as-illustrated in Figure 4. v

In order that the arms 3 may be rapidly and conveniently operated toperform'the closure operation described, the cam member 9 and the lever13 are providedfi As will be observed, by swinging the lever 13' with arotary movement, the arms 3 may be operated successively by a singlecomplete rotation of the lever. 1

Itis to be understood that the apparatus may be variously modified andembodied within the scope of'the subjoined claims.

I claim as my invent-ion.

1. Closure apparatus, comprising in combination, a base plate adapted tofit over a closure blank, a plurality of arms mounted thereon, said armsbeing provided with faces to engage the edges of said closure blank, andmanually operable means including a cam and lever for operating saidarms successively to crimp said edges to effect closure.

2. Closure apparatus, comprising in combination. a base plate adapted tofit over-a closure blank, a plurality of arms mounted gal thereon, saidarms being provided With faces to engage the edges of said closureblank, and means including a cam and lever for operating said armssuccessively with a single rotary motion of said lever to crimp saidedges to effect closure.

3. Closure apparatus, comprising in com-' bination, a base plate adaptedto fit over a closure blank, a plurality of levers pivoted thereon, saidlevers being provided with faces to engage the edges of said closure,and manually operable means including a cam and lever for operating saidarms successively to crimp said edges to effect closure.

4-. Closure apparatus, comprising in combination, a base plate adaptedto fit over a closure blank, a plurality of levers pivoted thereon, oneend of each of said levers being provided with a face adapted to engagethe edge of said closure blank, and the other end of each of said leversbeing provided with a face to engage an actuating means, and cam meansto engage said last named faces to actuate said levers successively tocrimp the edges of said blank to effect closure.

5. Closure apparatus, comprising in combination, a base plate adapted tofit over a closure blank, said plate being provided with a projectingflange forming a cup at the center thereof, a plurality of leverspivoted on said plate, said levers being provided at one end with facesto engage the edges of said closure blank and being provided at theirother ends with actuating faces extending within said cup through slotsin said flange, and means to operate said levers including a cam mountedloosely within said cup and a lever fixed to said cam.

6, Closure apparatus, comprising, in combination, a base plate adaptedto fit over a closure blank, an operating am looseh mounted on saidplate. a vertical operating lever secured thereto, a plurality of leverspivotally mounted on said plate, said levers being provided at one endwith a face to engage the edge of said closure blank and at the otherend with a face to engage said cam.

In testimony whereof, I have signed my name to this specification this5th day of January 1925.

JOHN J. ALEXANDER.
